Which of the following statement is/are correct for photoelectric effect
A. Photo current is depends upon intensity of light
B. Maximum kinetic energy of photo electron depends upon frequency of light incident on metal surface
C. If frequency of light incident on metal surface is equal to threshold frequency then photo electron must be ejected metal surface.
D. If-value of maximum K.E of photo `s^(-)` is `4.8xx10^(-10)J` then stopping potential is 3 volt.
